Randy Dunlap 0486d65804 efi: sysfb_efi: fix W=1 warnings when EFI is not set 
[ Upstream commit 19fdc68aa7 ]

A build with W=1 fails because there are code and data that are not
needed or used when CONFIG_EFI is not set. Move the "#ifdef CONFIG_EFI"
block to earlier in the source file so that the unused code/data are
not built.

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
